□ Identify Alt Leads
The first step in installation is to identify all the car
wires you’ll use when hooking up your sound
system.
As you identify each wire, we suggest that you
label it using masking tape and a permanent
marker. This will help avoid confusion when
making connections later.
Note: Do not connect the power connector to the
stereo unit until you have made all connections. If
there are no plastic caps on the stereo hooking
wires, insulate all exposed leads with electrical
tape until you are ready to use them. Identify the
leads as follows.
Turn the ignition on to the accessory position, and
ground one lead of the test bulb to the chassis.
Touch the other lead of the test bulb to each of the
exposed wires from the cut radio connector plug.
Touch one wire at a time until you find the outlet
that causes the test bulb to light.
Now turn the ignition off and then on. If the bulb
also turns off and on, that outlet is the car power
lead.
If your car is not wired for an audio unit:
Go to the fuse block and find the fuse port for
radio (RADIO), accessory (ACC), or ignition (IGN).
Battery Lead
If your stereo unit has a yellow lead, you will need
to locate the car’s battery lead. Othenwlse you may
ignore this procedure. (The yellow battery lead
provides continuous power to maintain a clock,
memory storage, or other function.)
If your car has a radio or is pre-wired for one:
With the ignition and headlights off, identify the car
battery lead by grounding one lead of the test bulb
to the chassis and checking the remaining
exposed wires from the cut radio connector plug.
If your car is not wired for an audio unit:
Go to the fuse block and find the fuse port for the
battery, usually marked BAT.
